Superficial siderosis of the central nervous system due to bilateral jugular vein thrombosis.

OBJECTIVE To describe a novel cause of meningeal siderosis due to intermittent subarachnoid bleeding caused by chronic bilateral jugular vein thrombosis. DESIGN Case report and review of literature. PATIENT A 51-year-old man with a distant history of cervical injury who presented with transient aphasia in the setting of progressive cognitive decline. INTERVENTION Neurological examination, magnetic resonance imaging, lumbar puncture, and angiogram. RESULTS The patient had intermittent subarachnoid bleeding resulting from extensive venous collaterals in the neck and cervical spine due to chronic bilateral jugular vein thrombosis. CONCLUSION Unexplained neurological deterioration and history of cervical trauma warrants diagnostic consideration of superficial siderosis and jugular vein thrombosis.
